As I really tore into the blazer for the first time I owned it in a bit under a year, I thought to myself that the factory skid plate sure would hold a lot of dirt and debris and be a great place for moisture to rot out the tank. A day after I'd thought that, I was removing the rear shackle hangers and noticed that the area around where the skid plate meets the tank was a bit damp. Sure enough, it's leaking gas. Now would be an appropriate time to upgrade the tank to something better tham OEM, but my main concern is ease of fueling up. I don't wish to drop the tailgate or do acrobatics to fuel up the blazer. Something that has crossed my mind is relocating the tank to inside the cab, but I'm not sure this is "legal"? I mean, in the event of a roll or flop there'd be gas everywhere. Plus I would hate smelling the fumes on long drives. I won't mind hacking up the body to relocate filler necks, but I'm not at all experienced with aftermarket tanks and how they would work. What are some alternatives to the OEM tank? Or, would an exact replacement for the tank be my best bet. Something else to consider since I don't know the history of my '91 blazer is how recently the fuel pump has been replaced. While the tank is out, I think it would be added insurance to replace the fuel pump. Any help or known alternatives would be great, Chad.
